如果將閘道設定為具有靜態路由的合作夥伴閘道,並將 ICMP 回應程式設定為追蹤這些路由的可連線性,則會提供 debug.py 命令來指出啟動或關閉狀態,如下所示:

vcadmin@vcg1-example:~$ sudo /opt/vc/bin/debug.py --icmp_monitor
{
  "icmpProbe": {
    "cTag": 0, 
    "destinationIp": "0.0.0.0", 
    "enabled": false, 
    "frequencySeconds": 0, 
    "probeFail": 0, 
    "probeType": "NONE", 
    "probesSent": 0, 
    "respRcvd": 0, 
    "sTag": 0, 
    "state": "DOWN", 
    "stateDown": 0, 
    "stateUp": 0, 
    "threshold": 0
  }, 
  "icmpResponder": {
    "enabled": false, 
    "ipAddress": "0.0.0.0", 
    "mode": "CONDITIONAL", 
    "reqRcvd": 0, 
    "respSent": 0, 
    "state": "DOWN"
  }
}
vcadmin@vcg1-example:~$

啟用 ICMP 回應程式時,關閉狀態表示沒有任何 Edge 連線至閘道。
